Chimney evaluation

The brick chimney has no liner. At the start of heating season I had furnace serviced, so I know combustion is good. Would it be best to use metal prefab liner or is it to old?

What do you mean by “is it too old?”, are you asking if your chimney is too old for a prefab liner? 
The age of your chimney is not a concern, its condition is. If it is structurally unsound it can fail / collapse no matter what type of a liner you’re going to install. So make sure it is structurally sound before investing into the liner installation.
You’d most likely need a stainless steel flexible tube, cap, top plate, and a tee. Depending on the exposure of your chimney - fully exposed / side wall or only partially (top section) exposed with majority concealed inside the house, and your local code requirements, you may or may not need an insulating sleeve.
There is a chimney liner installation video at the bottom of this page - http://checkthishouse.com/72/chimney-flue-furnace-water-heater-venting.html

Unsure about liner need.
